Corrosion Principles and Control Technology

• Introduction.
• Fundamentals of corrosion.
• Corrosion types.
• Corrosion forms.
• Corrosion control by design improving:

–  Simplifying the forms.

–  Avoiding the residual moisture.

–  Avoiding the galvanic corrosion.

• Corrosion control by change of metal:

–  Change of composition.

–  Change of structure.

–  Change of stress condition.

• Corrosion control by change in the corrosive medium :

–  Removal of corrosive constituents.

–  Addition of corrosion retarding substances.

• Corrosion control by change of the electrode potential :

–  Cathodic protection.

–  Anodic protection.
